ABSTRACT:
Drive unit for internal pipeline equipment, wherein the drive motor which drives the drive unit is disposed parallel to the pipe axis instead of transverse to the pipe axis, thereby to occupy a reduced space transverse to the length of the pipe and enabling a drive motor of given size to be used in a drive unit of smaller diameter than would be possible if the drive motor were disposed transverse to the pipe axis. In this way, drive units may be adapted for use in pipes of relatively smaller diameters than has heretofore been possible.
